The Mina Justa copper mine in Peru contracted Schenck Process to design, manufacture, supply and commission vibrating screens and feeders. The scope of the contract covers seven banana screens, five diverging pan feeders and one grizzly feeder and will leverage resources from business units located in Australia, China, South Africa and Chile, Schenck Process reported.

The screens include a number of mechanical and operational improvements developed on a prototype vibrating screen now undergoing site testing at an iron ore mine in Western Australia, the company reported. The five larger screens feature laminated side plates to maintain structural integrity and reduce stress concentrations associated with the projected process tonnages. Additionally, machined transition flanges are welded in a low stress area to the cross beams to actively reduce fatigue, and a unique spring removal system has been fitted to facilitate and reduce downtime during spring change-outs.

The six feeders have been designed to account for site conditions, Schenck Process reported. They are equipped with exchangeable liners and an upgraded transition hopper to improve operational availability and performance.
